Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or green in garden varieties), with either even or contrasting coloured tepals and corona.
Narcissus were popular in early civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten parts with approximately 50 species. The amount of species has assorted, depending about how they are classified, scheduled to similarity between kinds and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is undiscovered, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The types are native to meadows and woods in southern Europe and North Africa with a centre of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the late 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as slice blooms so when ornamental plants in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. Like other members of the family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if accidentally ingested. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as icons of spring. The daffodil is the countrywide blossom of Wales and the symbol of malignancy charities in many countries. The appearance of the untamed flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light bulb. They regrow in the following yr from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the light bulb. The place stem bears a solitary rose, but sometimes a cluster of bouquets (umbel). The bouquets, which can be usually conspicuous and white or yellowish, both or hardly ever inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may hang down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb lies dormant following the leaves and blossom stem die back and has contractile roots that draw it down further into the soil. The flower stem and leaves form in the light, to emerge the next season. Most species are dormant from warmer summer months to overdue winter, flowering in the planting season, though a few types are fall months flowering.
